| Abstract: | Using the concept of the of weighted residual method and choosing the fifth B-spline as a trial function to meet the needs of boundary conditions,the mechanical problem of large deflection of a rectangular thin plate is discussed. This method, compared with the traditional method of finite element, has the advantages of less unknown quantities,less degrees of freedom and high continuity and easy to satisfy boundary conditions as well. |
